MECHANISM FOR DRYING MACARONI.

Specification of Letters Patent.

Application filed-Octoberrl?, 1916. p erialii'o. 1243,0d2.

. 4 Vania, have invented Improved Mechanism for Drying'.Macaroni ing is a specieation. v

Our invention is designed for the )urpose ot' drying macaroni expeditiously, e ciently and econon'iicall)v with the production of an im roved product.

n the 'preferred practice ot' our invention, the macaroni is .sl'lspended b v means of racks in a closed compartment through which air is circulated with the aid ot' letlectors. This compartment communicates at itsl opposite' ends with a passage having,r a contracted throat containing a fan adapted to be op` erated in reverse directions for the purpose of reversing the air periodically in `the macaroni'compartment. the fan passage contain ot'which the following coils for circulating a heating tiuid to provide the circulatiiugr air with the desired temperature. A second passage is `connected with the fir.` passage b v valved ports and is provided with a t'an for. exhausting a desired amount of the air that has been used in the drying operation and taken ixp moisture from the macaroni. i

The vtemperature is preferably changed so that the air is alternately atvv a temperature of -from 6() to 70 degrees for about two hours While the oircillation is in one direction, and from to 105 degrees for the succeeding two hours, while the circulation is in the opposite direction. and so on through a period of approximately ten hours.

' t will be understood, however, that changes may be made in the structure and method of Jperation without departing from the spirit of our invention.

The nature and characteristic features of our improvements will be more fully understood from the following description and` the accompanying drawings in illustration` thereof.

In the drawings, Figure 1 is a vertlcal sectional view of mechanism embodying our" improvements; Fig. 2 is a broken horizontal' sectionalview taken on the line 2-2 of Fig. 1; Fig. 3 is a vertical sectional view taken on the line 8 3 oli Fig. l; and Fig. t 1a a broken horizontal sectional view italienon the line M of'Fig. 1.

Our invention, in the form thereotfillustiti trated in the drawings, embodies e' compartment l having end walls 2 with inneriaces inclininigf` trom the bottom 3 oi the chamber upwardly and outwardly to the level of the rateueeu een.. a; esta.,

top or ceiling 4t, which contains end ports 5 extending the width ofthe compartment.

The ports 5 connect the ends of the com partment 1, at its'top, with 'the endsot af 'titi passage formed by the sections 6 taperinigM oppositely to n throat 7, the passage having a circular opening 8 in its throat. Y

A fan 9. is adapted to be revolved in the vopening: 8 by means of the fanshatt 10 sections 6. for the circulation of a heatine fiuidand warmingn the air drawn or driven thereover by the tan 9.

The top or root 15 of the passage ti contain'sthe ports 16 controlled bythe valves 17 which are adjusted,conveniently by cords 18 passing therefrom over rollers 19 and throuofh the wall section Q to a )osition coni venent for mauipulationibv an operator.

A fan Q0 is disposed in a passage 21 in a wall 22.015 a chamber 23 above the ports i6 and is driven b v a motor 24. for the 'purpose of exhausting: moist ait from the system.

'A door 25, through 'which the travelingn racks 26 are adapted to move into and out of the compartment 1., permits a' certain amount of pure air to filter throughthe joints which it makes in the Wall', to replace toa greater or less degree that exhausted by the fan 20. i Tt will be understood that' in opera-tion the fun 9 is revolved by the motor i3 in one direction for say two hours and the air is circulated through the compartments 1" and 6in a course indicated by the arrows in Fig. 1, a part of the circulating air being drawn ott' through'the ports 16, passage and opening 21 by the fan 20 'for the pun pose of changing the air acting on the maca roni and remove moisture given up thereby.

lili"l verse to that indicated by the arrows, at the end o fwhieh period the operation is again rei'ersed and so on.

The form of the passage comprising the tapered sections 6 conduces to efficient circulation at a compa atirely high velocity or pressure :and 'etiicient distribution of the blastc in the macaroni compartment.

Tl1e temperature of the air to which the inacaronis subjected can be controlled as desired by operating the valves llt controlling the flow of heatingr fluid in thc coils 14.

Having described our invention, we claim:

l. The mechanism for dryingmacaroni which consists in a drying compartment, means forming' an air passage connnunicating therewith at both ends thereof, a fan for circulating air through said passage and compartment, and an exhaust chamber for drawing 0H' air circulated through said passage and compartment.

2. The mechanism for drying macaroni which consists in a drying compartment ha ving dmvnwardly converging walls and ports extending substantially across the top thereof, means forming' an air passage connnnnicating with said compartment through said ports and having converging walls forming a throat, a circulating coil in said passage, means for forcing! air through said passage and compartment and over said coil, an exhaust chamber eonmnlnieating with said air passage. means for controlling the communication between said chamber and passage, and a tan tor exhausting said chamber.

ln testimony whereof we have hereunto set. our names this tenth day of Octobery 1916.
